Scheldeprijs isn't a rough course but it's the last chance for racers to suss out equipment that will be used on Sunday at Paris-Roubaix. Here, Saxo-Tinkoff rider Michael Morkov apparently wanted to get some more saddle time on his Specialized S-Works Roubaix SL4 before the big day.

TRP R970EQ brakes and AceCo K-Edge number plate holders for UnitedHealthcare at Scheldeprijs.

Custom anodized and etched AceCo K-Edge chain catchers for UnitedHealthcare. AceCo's latest Professional design is more secure and can be easily adjusted independently of the front derailleur than the original setup.

It's a good thing UnitedHealthcare bikes have giant NeilPryde and Enve logos on them. Otherwise, a casual observer might instead mistake them for Sky's machines based on the color scheme.

Blanco uses custom made aluminum linear-pull brakes on its Giant Propel Advanced SL rigs instead of the molded carbon fiber ones found on production bikes. The more precise noodle socket, stronger return springs, and seemingly tighter tolerances lend a much improved feel at the lever.

Sprint shifters for Tyler Farrar (Garmin-Sharp) at Scheldeprijs. And don't fret about the "Vansummeren" sticker on the side of the computer. Team mechanics just wanted to make there was a computer on the bikes.

Europcar team mechanics used the rear brake housing stop to mount the number plate.

FDJ's Lapierre Xelius at Scheldeprijs.

This FDJ team-issue Lapierre Xelius cockpit is awfully busy with two computers - one from PRO and another from SRM - and the control box and satellite shifter for the Shimano Dura-Ace Di2 transmission.

Garmin-Sharp is one of several teams that have relied heavily on Gore's now-discontinued Ride-On sealed cable systems. Team mechanic Alex Banyay doesn't sound too worried, though. He says he has "a lot" of extra sets and liners on hand.

We've brought you plenty of enormous photo galleries covering top race bikes around the world but this one from Scheldeprijs is truly a beast – 138 images! Included in the mix is a close look at the Felt F-Series FRD of repeat winner Marcel Kittel (Argos-Shimano) plus the bikes of nearly every other team that was in attendance.

Scheldeprijs is the last warm-up event before Paris-Roubaix on Sunday. The parcours is essentially flat and mostly smooth but some riders still took the opportunity to do their final shakedown tests on slightly more unusual before hitting the treacherous cobbles of Arenberg.
